WASHING MACHINE.

Application filed Kay 81,

To all whom it may concern:

' Be it known that 1, JOHN E. KENNEY, an

citizen of the United States, and resident of-Portland, county of Multnomah, State of 'Oregon, have invented a certain new and My invention relates specificially to wash-.

ing machines which do not necessarily include a tub, but which are adapted to be mounted on any suitable tub.

' My invention in further particulars relates to washing machines of the dolly-head type that is .which comprise a rocking or oscillating head provided with pendant prongs or fingers by which engage the clothes and agitate them in the washing liquid. It; has been attempted heretofore to make said dolly head and its pendant fingers hollow, and to install a pump element in the dolly head or its pendant fingers. But with such arrangement, the water was alternately sucked into and then ejected again from said fingers. Such action tended to subject the clothes to undue wear, since when the pump exerted its suction action it tended fingers.

topull the clothes into the orifices of the Besides, the resistance offered to the pump action, while said orifices were covered by the clothes durin the suction stroke of the pump, tended to impose undue work on the latter.

The object of, my invention is to provide a washing machine of the character referred to in which said undesirable detrimental features are eliminated.

I attain my object by providing a hollow head and providing the latter with hollow pendant fingers, through which streams of the washing liquid are continuously ejected by the operation of a pump element located outside of the washing liquid, preferably mounted on the cover of the tub. In this way, the washing operation is facilitated by the simultaneous agitation of the clothes v and the ejection of the washing liquid Furthermore, I

through the latter, without the clothes being subjected to undue wear. 7 in order to facilitate the washing operation, I cause the streams of washing liquid ejected by the pendant fingers to be ejected with suflicient force to penetrate the clothes; and the same arrangement also tends to keep the clothes more or less spread out, that is to say, prevents it 1923. Serial No. 642,607.

from wadding up, which would tend to keep portions of the clothes out of contact with the washing liquid.

A further improvement of my invention has for its purpose the simplification of the devices operating the pump and simultaneously rocking the agitating head. The above mentioned and incidental features are hereinafter fully described and are illustrated in the accompanying drawings in which:

Fig. 1 is a plan view of my device mount ed on a hinged base and shows the pump and connecting mechanism in section 1, taken approximately on a line of 11 of Fig. 2. 1

Fig. 2, is a section taken on a line 22- of Fig. 1 and shows by arrows the approximate flow of water through the machine.

Fig. 2 is a view showing detail of construction.

Fig. 3, is a view taken on the line 3-3 of Fig. 2 and shows in dotted lines the approximate position of the oscillable washing head.

Fi 4, is a section taken on the line 4-4 of Fig. 3 and the arrows showingthe approximate circulation of the water through the tub.

portion 1 covers substantially the remainder. Ther is no mechanism mounted on section 1 and thus it can bereadily raised upward and thus provide easy access into the tub without lifting the mechanism. A prime mover, as the motor 2, is mounted on the base 1 and rotates the shaft 3. Another shaft 4 is held in axial alinement with the shaft 3 and is releasably connected thereto by means of a clutch 5. The male half 5 of the clutch is fixed to the shaft 3 and the female half 5 is slidably attached to the shaft 4 but is keyed against differential rotation therewith. A clutch lever 6 pivoted to theframe 7 of the mechanism, moves this clutch member 5 into and out of operative connection with the member 5. A worm 8 is mounted on the shaft 4 and meshes with the worm gear 9 which is mounted on vertical shaft 10 which is journaled in the REISSUED frame 7 at its upper and lower ends. The pump 11 is also mounted so as to be rotated by the shaft 4 and in the drawings we have shown this pump as a rotary pump which has a gear 12 mounted on the shaft 4 and an idling gear 13, meshing therewith. Thes'e gears rotate in a closely fitting casing 4 and draw water through the suction pipe 15 and force it up into the pipe 16. An arm 17 is mounted on the end of the shaft 10 and has a pin 18 aflixed near its end, the pin and arm forming a crank. The connect ing rod 19 is connected with this pin on one end and to the crank arm 20 on its opposite end, thus the rotation of the shaft 10 causes the oscillation of the crank 20. Crank 20 is integral with the hollow stub shaft-21, which is journaled in the tub top 1. I provide a plate 22 covering a relatively large portion of this cover, on which this stub shaft and crank bears so that wear may be reduced to the minimum. The oscillable washing head 23 is provided with a hollow shank 23" which is connected to the said stub shaft 21 by means of pin 24. The washing head is also hollow and is provided with a number of hollow prongs 25 which are perforated as 26. The pipe 16 extends into the hollow stub shaft 21 and the connection is made water tight by means of packing 27 which is held in place by a packing nut 28. Water is thus forced into the washing head and it escapes through the perforations 26. The supply of water for the pump 14 is obtained through the inlet pipe 15, which has perforations as 15. The suction pipe 15 lies closely along the side of the tub and the perforations 15 are preferably arranged on the inner face of this pipe so they will not be readily clogged by the clothes in the tub, thus a plentiful supply of water can alwa s be assured for the pump. As shown in ig. 2, prongs 25" for my device may be made with removable ends, as 27, which may be screwed into the 'end of the pron 25 at a point as 28. Thus the hollow was ing head and its prongs may be cleaned readily. I

The operation of my device is as follows: Power is obtained from the motor 12 which rotates the shaft 3, the shaft 4: can he connected so as to rotate therewith hy forcing in the. clutch 5. The shaft 4 in rotatin not only transmits power through the speed reduction gears, but also actuates the pump which causes water to flow through the device. lhe rotation of the worm 8 causes the rotation of the worm gear 9 which rotates the shaft 10 and thus the crank arm 17.

The rotation of the crank arm 17 and its pin 18 causes the longitudinal and angular movement of the connecting rod 19. The arm 20 is slightly longer thanthe crank arm 17 and thus the rotation of the shaft 10 causes only partial oscillating rotation be mounted on a tub, a pump, mounted on the-cover and provided with an outflow pipe, a rotatable hollow head depending centrally from said cover and into which said outflow pipe extends, said hollow head provided with pendant hollow perforated fingers, and means for oscillating said hollow head.
